#NewSpecies of #fish from #Antarctica highlights its threatened ecosystem https://phys.org/news/2024-08-species-antarctic-dragonfish-highlights-threatened.html

Akarotaxis gouldae, a new species of #Antarctic #dragonfish from the western Antarctic Peninsula https://mapress.com/zt/article/view/zootaxa.5501.2.3

"a population of #dragonfishes may have become isolated within deep trenches under #glaciers, surviving on food pushed in by the moving ice. Once the glaciers retreated, this subpopulation had become distinct enough to be reproductively incompatible with Akarotaxis nudiceps"

When searching for light and a mate in the deep, dark sea, male #dragonfish grow larger eyes https://phys.org/news/2024-07-deep-dark-sea-male-dragonfish.html

Sexually dimorphic eye size in #dragonfishes, a response to a bioluminescent signalling gap https://royalsocietypublishing.org/doi/10.1098/rsbl.2024.0165

Like many creatures that inhabit the dark #DeepSea, dragonfish survive thanks to numerous adaptations, including glowing #bioluminescence. But females are not quite as bright as males... male #fish have evolved larger eyes to find females who produce less light.
